completions for c99

[Vincent Lefevre]

c99 should be added to the command list of
"functions/Completion/Unix/_gcc".

Note: c99 is the name of the C compiler specified by POSIX.

That would cause several hundred options to be offered, but on some
systems c99(1) supports far fewer options:

https://pubs.opengroup.org/onlinepubs/9699919799/utilities/c99.html
https://www.freebsd.org/cgi/man.cgi?query=c99&manpath=FreeBSD+12.1-RELEASE

We probably need a bit of $service-specific code, to see whether c99(1) is
in fact gcc or clang, in which case we can fall back to offering all
their options, or not, in which case we should offer just the handful of
options that's in fact supported.

Anyone interested in writing the patch?

Note that POSIX lists the minimum that needs to be supported.

I've noticed that cc is in the list, and on some platforms, it may
also support fewer options. This can even include Debian machines,
where cc is (at least) either gcc or tcc, depending on the system
configuration.
